RoseTracker| People who sleep less than six hours a night are three times more likely to develop the precondition to diabetes and heart disease than those who stay down for six to eight hours.
The condition is known as IFG or incident-impaired fasting glycaemia, which is a glucose-regulating deficiency. People with IFG have a significantly higher risk of developing type 2 diabetes and are at increased risk of heart disease and stroke.
More research is required, but lead author at Warwick Medical School Dr Saverio Stranges believes there is now a strong correlation between lack of sleep, type 2 diabetes and heart disease. via Science Daily
Note: sleep more than eight hours is ALSO a strong predictor of enhanced risk for diabetes. Read separate study.
